Hi Marc...
And your hollidays?!? starts this afternoon?
For Linux (and MPEG4), you can see at mplayer (www.mplayerhq.hu).
It's THE media player for linux! ;-)
Very powerfull, a lot of codecs, gui/non-gui, some hardware acceleration
(possibility to use openGL, but I don't know what for).
I don't know if it's GPL, but you can find sources at their site.
On my computer, it runs divX at 1% cpu! (Athlon 1800+, audio+video)
I think the 99% left could be sufficient for rendering 3d...
With openGL extentions about rendering to texture, you may just make the
video output of Mplayer point to your texture pBuffer, and play with it.
Never tested, but I know it's possible (i've tryed effectv, which render
realtime effects on a video strem (from movie camera, tv, webcam...),
and can display as texture for a cube. So, render to texture - using
this texture is possible in realtime with a lot of other things charging
the cpu (your mpeg4 decompression))
good hollidays!
;-)
